Bug fix on Swift -- 3

We have identified bugs in swift (converted from React) and need the help of an experienced Swift and React native person to resolve them. Specifically, some feature inconsistencies in UI and some functionality show inconsistency. The specialist should resolve them (may need to recompile current code) and update existing website to reflect UI and design changes in swift app. The urgency of this project is medium.
There are two more phases (projects) that will follow this bug fix and will be budgeted separately.
